Photographic lens system

ABSTRACT

An improved compact telephoto type lens system is provided, including a front lens group of a positive refractive power having at least four lens components with one of the lens components having an aspheric surface and a rear lens group of a negative refractive power. The aspheric lens component can be a composite lens component of a glass substrate with a thin plastic aspheric surface.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a photographic lens system, and more particular to a photographic lens system suitable for 35 mm lens-shutter camera.

2. Description of the Prior Art

Recently, in the field of 35 mm lens-shutter cameras, compactness thereof is a highly desired design characteristic, and therefore, compactness of the photographic lens for 35 mm lens shutter cameras is also required. In this circumstance, an telephoto type lens system which comprises a negative front lens group and a positive rear lens group, is known as a lens system suitable for compactness, and is applied in many lens-shutter cameras. However, aperture ratios of almost all of the known telephoto type lens system are equal to or less than 1:2.8.

Thus, if the aperture ratio of the lens system can be increased, it would enable photography in lower light conditions, and to extend the photographic permissible distance range in flash photography.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a photographic lens system having an aperture ratio of about 1:1.9, a field of view of about 64°, and a good correction of aberrations.

In the telephoto type lens system, it becomes a problem to correct the spherical aberration and the distortion when providing a large aperture ratio. Especially, with respect to the spherical aberration, it is necessary to overcome two problems as follows: a first problem is to correct the deterioration of the spherical aberration due to the large aperture ratio and a second problem is to correct the change of the spherical aberration due to the focusing operation, when the front lens group is shifted for focusing. To solve the the second problem, it is necessary to correct the spherical aberration well within the front lens group. Therefore, it is effective for correcting the spherical aberration to construct the front lens unit by at least four lens components and to introduce at least an aspheric lens surface to the front lens unit.

Thus, according to the present invention, the photographic lens system comprises from the object side to the image side, a front lens unit of a positive refractive power including at least four lens components with at least one surface having an aspheric surface, and a rear lens unit of a negative refractive power all of whose refractive surfaces are spheric, wherein the lens system fulfills the following condition when 0.5 R_(F) <h<R_(F) is maintained: ##EQU1## wherein, h represents the height from the optical axis, t_(F) (h) represents the thickness of the lens component having the aspheric surface in the front lens unit on the height h, r_(k) represents the paraxial radius of curvature of the object side surface of the lens component having the aspheric surface in the front lens unit, r_(l) represents the paraxial radius of curvature of the image side surface of the lens component having the aspheric surface in the front lens unit, d_(F) represents the axial thickness of the lens component having the aspheric surface in the front lens unit, and R_(F) represents the minimum value among |r_(k) |, |r_(l) |, and the effective height of the aspheric surface of the front lens unit.

The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operator, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is provided to enable any person skilled in the optical and camera field to make and use the invention and sets forth the best modes contemplated by the inventors for carrying out their invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide a relatively economical and easily manufactured compact zoom lens system. The derivation of the formulas and the relation of the powers set forth herein can be accomplished with the assistance of a computer. The present invention represents the parameters of a compromise balance of acceptable aberrations which can be relatively easily manufactured to provide a low cost lens system for utilization with a 35 mm lens-shutter camera.

In the drawings, schematic cross sectional views disclose the position of the lens groups and lens elements. Due to the number of lens elements involved, it was not deemed appropriate to include individual designation of the radii of curvature and axial distances for each lens element and air space. These values, however, are provided in the accompanying tables set forth herein, and the schematic cross sectional views of the respective embodiments follow the normal conventions of an object at the left-hand side of the drawing and the image plane at the right-hand side.

As shown in FIGS. 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85 and 87, according to the present invention, the photographic lens system comprises from the object side to the image side, a front lens unit of a positive refractive power including at least four lens components (G₁) to (G₄) with at least one lens component having an aspheric surface, and a rear lens unit (G₅) of a negative refractive power all of whose refractive surfaces are spheric, wherein the lens fulfills the following condition when 0.5 F_(F) <h<R_(F) is maintained: ##EQU2## wherein, h represents the height from the optical axis, t_(F) (h) represents the thickness of the lens component having the aspheric surface in the front lens unit on the height h, r_(k) represents the paraxial radius of curvature of the object side surface of the lens component having the aspheric surface in the front lens unit, r_(l) represents the paraxial radius of curvature of the image side surface of the lens component having the aspheric surface in the front lens unit, d_(F) represents the axial thickness of the lens component having the aspheric surface in the front lens unit, and R_(F) represents the minimum value among |r_(k) |, |r_(l) |, and the effective height of the aspheric surface of the front lens unit.

Condition (1) limits the configuration of an aspheric lens component having an aspheric surface in the front lens unit, and is effective for correcting the spherical aberration, especially for correcting the spherical aberration with respect to the marginal light rays. If the condition (1) is violated, it becomes very difficult to well correct the spherical aberration with respect to the marginal light rays. Here, the limitation of 0.5 R_(F) <h<R_(F) means that, in the large aperture ratio lens system, the configuration of the relatively large height of the aspheric lens component in the front lens unit is important for correcting the spherical aberration with respect to the marginal light rays.

Furthermore, it is effective for properly correcting the distortion to introduce a rear lens component having an aspheric surface to the rear lens unit. Especially, the following condition is effective for correcting the distortion well when 0.4 R_(R) <h<R_(R) is maintained; ##EQU3## wherein, t_(R) (h) represents the thickness of the rear aspheric lens component on the height h, r_(m) represents the paraxial radius of curvature of the object side surface of the rear aspheric lens component, r_(n) represents the paraxial radius of curvature of the image side surface of the rear aspheric lens component, d_(R) represents the axial thickness of the rear aspheric lens component, and R_(R) represents the minimum value among |r_(k) |, |r_(l) |, and the effective height of the aspheric surface of the rear aspheric lens component.

Condition (2) limits the configuration of the rear aspheric lens component. If condition (2) is violated, it becomes very difficult to properly correct the distortion. Here, the limitation of 0.4 R_(R) <h<R_(R) means that, since the distortion is increased according to the increase of the field of view in the telephoto type lens system, the configuration of the relatively large height of the rear aspheric surface is important for properly correcting the distortion in the middle and marginal area.

Contrary, if an aspheric surface is not applied to the rear lens unit, to appropriately correct the distortion, it is desirable that the rear lens unit includes a negative lens component concave to the object side, and that the following condition is satisfied:

    -0.75<φ·r.sub.R <-0.15                        (3)

wherein, φ represents the refractive power of the whole lens system, and r_(R) represents the radius of curvature of the object side surface of the negative lens component. If the upper limit of condition (3) is violated, it is difficult to correct the distortion, since the positive distortion is increased. If the lower limit of condition (3) is violated, although the positive distortion is appropriately corrected, the total length of the lens system is extended undesirably.

In addition to the above conditions (1) and (2), a plurality of lens arrangements and conditions for achieving higher performance will be explained.

A first lens arrangement is constructed as follows: the front lens unit includes from the object side, a positive first lens component (L₁) convex to the object side, a negative second lens component (L₂), a third lens component (L₃) having at least an aspheric surface, and a positive fourth lens component (L₄), and the rear lens unit includes a negative fifth lens component (L₅) concave to the object side, as shown in Embodiments 1, 2, 3, 4, 5, 6, 7, 8, 27, 28, 29, 30, 31, and 32 described below. And the following condition is effective for the first lens arrangement:

    -1.0<φ.sub.3 /φ<1.0                                (4)

wherein, φ₃ represents the refractive power of the third lens component, and φ represents the refractive power of the whole lens system.

Condition (4) is effective for correcting the spherical aberration, for obtaining the sufficient marginal illumination, and for shortening the total length of the lens system. If the upper limit of condition (4) is violated, the spherical aberration is considerably generated in the marginal area, and therefore, the image point is shifted considerably according to the the change of the aperture diaphragm. If the lower limit of condition (4) is violated, it is difficult to obtain the sufficient marginal illumination, and the total length of the lens system is extended undesirably.

In the first arrangement, it is desirable to satisfy the following conditions:

    -2.0<φ.sub.F /φ.sub.R <-1.0                        (5)

    -1.7<φ.sub.b /φ<0                                  (6)

wherein, φ_(F) represent the refractive power of the front lens unit, φ_(R) represents the refractive power of the rear lens unit, and φ_(b) represents the refractive power of an air lens formed between the second and third lens components.

Condition (5) limits the refractive power balance between the front and rear lens units for correcting the field curvature and the sagittal flare in the middle area. If the upper limit of condition (5) is violated, the negative field curvature is generated considerably, since the Petzual sum becomes a large positive value. If the lower limit of condition (5) is violated, since the Petzual sum becomes too small, the flare of the saggital rays is generated in the middle area.

Condition (6) is effective for properly correcting the coma. If the upper limit of condition (6) is violated, the outer coma is generated undesirably. If the lower limit thereof is violated, the inner coma is generated considerably.

A second lens arrangement is constructed as follows: The front lens unit includes from the object side, a positive first lens component (L₁) convex to the object side, a second lens component (L₂) having at least an aspheric surface, a negative third lens component (L₃), and a positive fourth lens component (L₄), and the rear lens unit includes a negative fifth lens component (L₅) concave to the object surface, as shown in Embodiments 9, 10, 11, 12, 13, 14, 33, 34, 35, and 36 described below. And the following condition is effective for the second lens arrangement.

    -1.0<φ.sub.2 /φ<1.0                                (7)

wherein, φ₂ represents the refractive power of the second lens component, and φ represents the refractive power of the whole lens system.

Condition (7) limits the refractive power of the second lens component having an aspheric surface. If the upper limit of condition (7) is violated, the spherical aberration is considerably generated in the marginal area, and therefore, the image point is shifted considerably according to the change of the aperture diaphragm. If the lower limit of condition (7) is violated, it is difficult to obtain the sufficient marginal illumination, and the total length of the lens system is extended undesirably.

In the second lens arrangement, it is desirable to further satisfy the following conditions:

    -2.0<φ.sub.F /φ.sub.R <-1.0                        (8)

    -2.0<(φ.sub.a +φ.sub.b)/φ<-0.5                 (9)

wherein, φ_(F) represents the refractive power of the front lens unit, φ_(R) represents the refractive power of the rear lens unit, φ_(a) represents the refractive power of an air lens formed between the first and second lens components, and φ_(b) represents the refractive power of an air lens formed between the second and third lens components.

Condition (8) limits the refractive power balance between the front and rear lens units for correcting the field curvature and the sagittal flare in the middle area. If the lower limit of condition (8) is violated, the negative field curvature is generated considerably, since the Petzual sum becomes a large positive value. If the upper limit of condition (8) is violated, since the Petzual sum becomes too small, the flare of the sagittal rays is generated in the middle area.

Condition (9) limits the sum of the refractive power of an air lens formed between the first and second lens components and the refractive power of the other air lens formed between the second and thrd lens components. The condition (9) is effective for correcting the coma and the distortion in middle area. If the lower limit of condition (9) is violated, the outer coma is increased considerably. If the upper limit of condition (9) is violated, the inner coma is increased considerably, and the positive distortion is generated in the middle area.

A third lens arrangement is constructed as follows: the front lens unit includes from the object side, a positive first lens component (L₁) convex to the object side, a negative second lens component (L₂), a positive third lens component (L₃), and a fourth lens component (L₄) having at least an aspheric surface, and the rear lens unit includes a negative fifth lens component (L₅) concave to the object side, as shown in Embodiments 15, 16, 17, 18, 19, 20, 37, 38, 39, and 40 as described below. And the following condition is effective for the third lens arrangement:

    -1.0<φ.sub.4 /φ<1.0                                (10)

wherein, φ₄ represents the refractive power of the fourth lens component, and φ represents the refractive power of the whole lens system.

Condition (10) limits the refractive power of the fourth lens component having an aspheric surface. If the upper limit of condition (10) is violated, the spherical aberration is considerably generated in the marginal area, and therefore, the image point is shifted considerably according to the change of the aperture diaphragm. If the lower limit of condition (10) is violated, it is difficult to obtain the sufficient marginal illumination, and the total length of the lens system is extended undesirably.

In the third lens arrangement, it is desirable to satisfy the following conditions:

    -2.0<φ.sub.F /φ.sub.R <-1.0                        (11)

    0<φ.sub.c /φ<1.5                                   (12)

wherein, φ_(F) represents the refractive power of the front lens unit, φ_(R) represents the refractive power of the rear lens unit, and φ_(c) represents the refractive power of an air lens formed between the third and fourth lens components.

Condition (11) limits the refractive power balance between the front and rear lens units for correcting the field curvature and the sagittal flare in the middle area. If the lower limit of condition (11) is violated, the negative field curvature is generated considerably, since the Petzual sum becomes a large positive value. If the upper limit of condition (11) is violated, since the Petzual sum becomes too small, the flare of the sagittal rays is generated in the middle area.

Condition (12) is effective for properly correcting the coma. If the lower limit of condition (12) is violated, the outer coma is generated undesirably. If the upper limit thereof is violated, the inner coma is generated considerably.

A fourth lens arrangement is constructed as follows: the front lens unit includes from the object side, a first lens component (L₁) having at least an aspheric surface, a positive second lens component (L₂) convex to the object side, a negative third lens component (L₃) and a positive fourth lens component (L₄), and the rear lens unit includes a fifth lens component (L₅) concave to the object side, as shown in Embodiments 21, 22, 23, 24, 25, 26, 41, 42, 43 and 44 described below. And the following condition is effective for the fourth lens arrangement:

    -1.0<φ.sub.1 /φ<1.0                                (13)

wherein, φ₁ represents the refractive power of the first lens component, and φ represents the refractive power of the whole lens system.

Condition (13) limits the refractive power of the first lens component having an aspheric surface. If the upper limit of condition (13) is violated, the spherical aberration is considerably generated in the marginal area, and therefore, the image point is shifted considerably according to the change of the aperture diaphragm. If the lower limit of condition (13) is violated, it is difficult to obtain a sufficient marginal illumination, and the total length of the lens system is extended undesirably.

In the fourth lens arrangement, it is desirable to satisfy the following conditions when an aspheric surface is introduced to the rear lens unit:

    -2.0<φ.sub.F /φ.sub.R <-1.0                        (14)

    -2.0<φ.sub.b /φ<-0.2                               (15)

wherein, φ_(F) represents the refractive power of the front lens unit, φ_(R) represents the refractive power of the rear lens unit, and φ_(b) represents the refractive power of an air lens formed between the second and third lens components.

Condition (14) limits the refractive power balance between the front and rear lens units for correcting the field curvature and the sagittal flare in the middle area. If the lower limit of condition (14) is violated, the negative field curvature is generated considerably, since the Petzual sum becomes a large positive value. If the upper limit of condition (14) is violated, since the Petzual sum becomes too small, the flare of the sagittal rays is generated in the middle area.

Condition (15) is effective for appropriately correcting the coma. If the lower limit of condition (15) is violated, the outer coma is generated undesirably. If the upper limit thereof is violated, the inner coma is generated considerably.

Furthermore, the following conditions are effective for all of the first to fourth lens arrangements.

    0.6<φ.sub.P /φ<1.5                                 (16)

    -1.1<φ.sub.R /φ<-0.3                               (17)

wherein, φ_(P) represents the refractive power of the lens component which is located at the most object side among the lens components of a positive refractive power without having an aspheric surface.

Condition (16) is effective for making the lens system compact and for achieving a large aperture ratio while maintaining a good correction of the spherical aberration. If the upper limit of condition (16) is violated, the spherical aberration is in an under correcting condition, and therefore, it could not be corrected properly even if an aspheric surface is introduced to the front lens unit. If the lower limit thereof is violated, the total length of the lens system is extended considerably.

Condition (17) limits the refractive power of the rear lens unit for correcting the field curvature and the sagittal flare in the middle area. If the upper limit of condition (17) is violated, the negative field curvature is generated considerably, since the Petzual sum becomes a large positive value. If the lower limit of condition (17) is violated, since the Petzual sum becomes too small, the flare of the sagittal rays is generated in the middle area.

Furthermore, if an aspheric surface is not applied to the rear lens unit, the above first to fourth lens arrangements and the conditions (4) to (17) are effective in addition to the conditions (1) and (3).

In the present invention, the aspheric lens component having an aspheric surface is made by grinding and polishing an optical glass material to the predetermined aspheric surface configuration, or by coating a thin layer having the predetermined aspheric surface configuration on a spheric surface of the glass lens component, or by molding a synthetic resin material to form the aspheric lens component. The last method which uses the mold is, however, the most favorable in view of the low manufacturing cost and the light weight of the lens component. Here, the synthetic resin material has a large coefficient of thermal expansion and a large dimensional change due to the temperature change thereof, when comparing to a glass material. Therefore, in the present invention, it is desirable that the refractive power of the lens component made of the synthetic resin material is relatively weak.

The other problem occurred when the lens component is manufacturing by molding the synthetic resin material is that the molded lens component is distorted by the thermal contraction of the synthetic resin material in the cooling procedure of the molding method. Therefore, it is desirable that the difference in thickness between the central portion of the lens component and the marginal portion thereof is small. Therefore, if the aspheric lens component having the aspheric surface is made of the synthetic resin material, it is desirable to fulfill the following conditions:

    -0.4<φ.sub.f /φ<0.4                                (18)

    -2.0<φ.sub.g /φ<0                                  (19)

    φ·|t.sub.F (h.sub.F)-d.sub.F |<0.05 (20)

    φ·|t.sub.R (h.sub.R)-d.sub.R |<0.16 (21)

wherein, φ represents the refractive power of the whole lens system, φ_(f) represents the refractive power of the front aspheric lens component having an aspheric surface in the front lens group, φ_(g) represents the refractive power of the rear aspheric lens component having an aspheric surface in the rear lens group, t_(F) (h_(F)) represents the thickness of the front aspheric lens component in the height h_(F), and t_(R) (h_(R)) represents the thickness of the rear aspheric lens component in the height h_(R).

Conditions (18) and (19) limit the refractive powers of the aspheric lens components, respectively, for decreasing the shifting of the image point due to the temperature change. If conditions (18) and (19) are not satisfied, the image point is considerably shifted in accordance with the temperature change.

Conditions (20) and (21) limit the configurations of the aspheric lens components, respectively. If conditions (20) and (21) are not satisfied, the optical performance of the whole lens system is influenced undesirably by the thermal contraction of the synthetic resin material.

Here, if the camera body is made of the synthetic resin material, the distance from the lens system to the film plane is normally extended in accordance with the increase of temperature. Thus, it is favorable to expect the influence of such extension by constructing the lens system so that the distance from the lens system to the image plane is extended according to the increase of temperature. In doing so, it is desirable that the refractive power of the front aspheric lens component made of the synthetic resin material is positive in addition to conditions (18) and (19).

The following Tables 1 to 44 disclose, respectively, the first through forty-fourth embodiments of the present invention. In the Tables, f equals the focal length, r is the radius of curvature with respective sub numbers indicating the surfaces from the object to image side along the optical axis, d represents the axial distance and includes both the air spaces and the actual thickness of the lenses along the optical axis, N equals the refractive index and again, the sub numbers refer to the particular optical element from the object to image side, and finally, ν equals the Abbe number and the sub numbers refer to the specific lens elements from the object to image side. The asterisk (*) (**) represents the aspheric surface, and its coefficients are shown at the bottom of respective Tables.

Here, the aspheric coefficients are defined by the following equation: ##EQU4## and wherein r_(i) represents the paraxial radius of curvature, of the basic spheric surface, X represents the coordinate along the optical surface measured from the top of the basic surface, and Y represents the coordinate perpendicular to the optical axis measured from the optical axis. In the tables, ΔF and ΔR are defined as follows: ##EQU5##

In the present invention, the front lens unit is shiftable along the optical axis for focusing, however, the whole lens system may be used for focusing. Additionally, a part or the entire whole of the rear lens unit can be used for focusing.

In the present invention, each of the lens component are not limited to a single lens element, and may include a compound lens element.

Additionally, the Table 45 shows the value of all embodiments with respect to the parameter of condition (16) and (17).
